Flax seed is a rich source of many nutrients, including protein, fiber,
mucilage, trace minerals and more omega-3 fatty than fish oil. Flax seed
is also abundant in a class of plant compounds called lignans, which are
potent antioxidants with phytoestrogenic properties. In order to benefit
from the dietary fiber, however, it is necessary to grind the seed.
Aside from being a source food and fiber for cloth and paper, flax has
been used for other practical purposes. During times of flood, for
example, flax seed has been stuffed into sacks to absorb water and
purposely block drains to reduce the threat of sewer backup. Once the
floodwater receded, a string tied to the sack ensured its later
retrieval.
